You can share your thoughts about a friend's photos by leaving him/her a comment. To do this, you'll need a Google Account for Picasa Web Albums. Once you're signed in, follow these steps:
- Select a photo.
- Write your comment in the text box that appears under the photo.
- Click the box next to 'Subscribe' to receive an email notification when someone else comments on the photo thread.
- Click Post Comment.
Comments are visible to everyone that views the photo. While you can't edit a comment after you submit it, you can delete it at any time. In addition, the owner of the album can delete your comments by clicking delete to the right of the comment.
